Title: Method for confirming receiving of Protocol data
Inventor: LEE SEUNG JUN
IPC: H04L12/28
Filed: 2000-07-01
Abstract: PURPOSE: A method for confirming reception of protocol data is provided so that the system cannot be overloaded by overcoming start point falling in a window-based falling algorithm and reducing falling in the system. CONSTITUTION: Tx_window_size and Poll_window are transmitted from an upper layer to a radio frequency link control layer(S21). The radio frequency link control layer renews VT(A) according to an acknowledge signal from a reception terminal(S22). VT(MS) is calculated according to VT(A)+Tx_window_size(S23). VT(S) is increased by '1' whenever a protocol data unit is transmitted from the radio frequency link control layer(S24). When VT(A) is smaller than or equal to VT(S) and when VT(S) is larger than VT(MS), a protocol error is generated and reported to the upper layer(S26). When VT(A) is smaller than or equal to VT(S) and when VT(S) is smaller than VT(MS)(S25), transmission of a falling signal is determined by Formula 3 or 4(S28). When Formula 3 or 4 is greater than Poll_size(%), the falling signal is transmitted from a transmission terminal to the reception terminal(S29). When it is smaller than Poll_size(%), the radio frequency link control protocol data unit is continuously transmitted(S30). The reception terminal confirms which of the radio frequency link control protocol data units is received(S31).
